## The Ssum – Phone Call Timetable

In The Ssum, there would be an incoming call from Teo, or you can call Teo.  
However, sometimes he would not pick up the phone. Or, sometimes it needs to pick a specific choice to unlock the phone calls.

Therefore, in order to save everyone's batteries (lol), it is the phone call timetable and requirements 🙂

This is the dashboard.  
The green is the incoming call from Teo, and the orange is the outgoing call to Teo. If there is no call, then it would be marketed as “-“. Also, if the phone call has some specific requirements, then it would be shown in red and the required response is also recorded in the sheet.  
Feel free to add comments to the sheet!

Calls shown with a red left border require a specific chatroom choice to unlock.
